I'm sort of curious on if you really think these two things are apt for comparison: the societal / biological containment of covid, vs. the societal / biological containment of the bubonic plague. I haven't read about the black plague in a while, but I think I remember something about people getting covered in massive sores, and maybe getting disfigured by it somehow, as well. Something tells me that the effects of the black plague were more ostensible, and, I suppose, it probably was more upfront in terms of lethality.
So the question I had, was how would a dark ages era population react to covid, in place of the black plague? Would they fold in with the general instability of their mortality due to other factors, general to the time, taking it more in stride, or would they start breaking out the bird beaks
